FOOT FOR SEWING MACHINES.

Application filed April 4, 1921.

To all whom it may concern:

Be it known that I, Mounts J. BERG, a citizen of Poland, residing at St.Paul, in the county of Ramsey and State of Minnesota, have invented newand useful linprovements in Feet for Sewing Machines, of which thefollowing is a specification.

Sewing machines in common use for heavy service employ fourinterchangeable feet to guide and hold the fabric beneath the needle.These feet, viz, a plain solid foot a plain swinging foot, 21. solidgauge foot and a swinging gauge foot are used during different stages ofwork and must frequently be exchanged one for another during the processof making or repairing a garment. Such interchange of parts necessitatesreadjustment and results in loss of much valuable time.

It is my object to save inconvenience and loss of time by providing anefficient foot to take the place of the four feet formerly used.

A further object of my invention is to provide a single foot which maybe quickly adapted to do the work of a solid or swinging, gauge or plainfoot.

Other objects of my invention will appear and he more fully pointed outin the following specification and claims.

T he drawings forming part of this specification illustrate what I atpresent believe to be the best form of my device but it will beunderstood that modifications are possible within the spirit of myinvention.

Referring to the accompanying drawings Figure 1 is a perspective view ofmy improved foot mounted on a sewing machine of common type; Fig. 2 is aplan View of the same detached from the machine; Fig. 3 is a sideelevation of the same; Fig. .t is an end view of the same; Fig. 5 is asection taken on the line of Fig. 3; Fig. 6 is a detail perspective viewof the detachable prong and Fig. 7 is a similar view of the gauge whichmay be substituted for the detachable prong shown in Fig. 6.

My improved foot is designed to be fastened in the usual manner to thesquared lower end of the spindle 1 of the sewing machine by means of ascrew '2' which engages a channel 3 on the sides of aslot at. Thischannel 3 is adapted to receive the squared lower end of the spindle 1and is formed integral with a shank 5 of the foot. A central bodyportion 6, integral with the Serial No. 458,382.

projects at right angles to said shank to form a support for the loweror swinging part 7 of the foot. The part 7 is formed with a pair ofupwardly projecting ears 8 and a rigid prong 9 and its lower surface issmooth to form a bearing for the fabric to be sewed. The cars 8 aretiltably connected to the body 6 by means of a pin 10 which passesthrough suitable perforations in said ears and body, and a set screw 11in a tapped hole in one of the ears 8 is provided to engage the body 6and hold said body and the part 7 in the full line position shown inFig. 3 when it is desired to use the foot in its rigid or solidcapacity. The inner end of the screw 11 is formed to enter a suitablerecess in the body (3 when the lower part 7 is in the full line positionshown in Fig. 3. A. stop comprising a lug 12 on the part 7 and acoa-cting lug 13 on the body 6 is provided to limit the tilting motionof the part 7 on the pin 10 when the foot is used in its swingingcapacity.

A removable prong 1% similar to but slightly shorter than the prong 9 isformed with a tongue 15 which may be inserted in a suitable groove inthe part 7 beneath the ears 8. When thus inserted the prong 141 is heldin place by a pair of springs 16 mounted on the ears 8 and a flange 1'?on the end of said tongue which engages the outer edge of the rigidprong 9 (see Figs. 5 and When desired, a gauge 18 may be substituted forthe rigid prong l l by removing said prong and inserting the end 19 ofsaid gauge in the groove beneath the spring 16.

lln operation my improved foot is mounted on the spindle 1 of the sewingmachine by means of the screw 2 as described above. If a plain solidfoot is needed. the prong 1a is mounted adjacent to the prong 9. asshown in Figs. 2, 3 and l and the screw 11 is tightened so as to fastenthe lower part 7, carrying the prongs 9 and it. to the body (5. Thisholds the foot in the position shown in the full lines in Figs. 2-, Sand -.l-. W hen 1 plain swinging foot is needed the screw 1' isloosened. and, the prong ll being in plac beside the prong 9, the lowerpart "4' is fre to tilt on the body 6 to permit the foot to pass overobstacles such as heavy seams and the like. To adapt the foot for usewith the gauge 18, it is only necessary to remove the prong 1%, againstthe action of the spring; 16, and to substitute the gauge therefor. Thegauge foot may be made either swinging or sOllCl by loosening ortightening' the screw 11 described above.

laying described my invention What I claim as new and desire to protectby Letters Patent is 1. In a device of the class described a shankformed with a body extending at an angle therefrom a p'rOnp formed withup- Wardly to said body, said ears being formed with recesses adapted toreceive a second prong or a gauge, a second prong formed with a shorttongue adapted to be inserted in said recess and means for removablyholding said prong or gauge within said recess.

)ro'ectin ears tiltabl connected 2. In a device of the class described,a shank having a bodyextending at an angle therefrom on its lower end, aprongformed with upwardly projecting ears tiltably connected to saidbody, said ears being formed with recesses-adapted to receive a secondprong or a gauge, a second prong formed With a short tongue adapted tobe inserted in said recess, means for rcmovably holding aid prone orgauge Within said recess and a' screw '1' ged to be manipulated torigidly secure said first mentioned prong to said shank.

In testimony whereof, I have hereunto signed my name to thisspecification.
